Hi , We are using water wash solder paste to solder the SMT LED's manufactured by Chicago Miniature lamp (CMD93-21 & 22)and Kingbright. Achieving the solder fillet , wetting has no issue but we observe high fallout at the functional testing. If we do

We found a PCBA performance have insertion loss at the functional test process. We did some analysis and conclude the main root cause is from the PCB performance. What is the critical parameter in PCB will cause a failure in PCBA frequency performan

Last year we installed two in-line ICT/Functional testers. With the current volume getting ever greater, we need to be able to identify post test what has been tested and what has not. One idea was to put two circular pads 0.100 apart with an 0.004"

Trying to get a sense of the push-pull going on between designers and manufacturers on the subject of 'one test point per net'. Getting a feeling like the new paradigm is doing all of the electrical tests as functional at EOL and relying almost comp

Depends on what sort of outfit you are working for, and what you are building. A lot of CEMs are doing Flying Probe or ICT on the boards ahead of investing time building into units or adding parts that prevent access to rework. We have a combination

Welcome to the forum. Yes, there is a wide range of equipment types that can be used to measure the function of components after the board is assembled. Look here for test: http://circuitsassembly.com/bguide/

Hi all Wonder if anyone can help , I'm trying to test a pcb board ( with very little experience) I've tested the resistors and now the capacitors , only to find that about 5 of them have continuity so guessing there not working . I checked the s
